Specific embodiment
With reference to the accompanying drawing and the principle of the present invention and structure is described in detail in embodiment.
In the description of the present invention, it is to be understood that, term " on ", "lower", "front", "rear", "top", "bottom",
The orientation or positional relationship of the instructions such as "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of retouching
It states the present invention and simplifies description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific
Orientation construction and operation, therefore be not considered as limiting the invention.
The invention proposes the mounting structures of a kind of valve seat and pipe fitting, include pipe fitting 1, connector in figure as shown in Figures 1 to 3
2, valve seat 3 and fastener 4, valve seat 3 are mounted in valve body 6, and pipe fitting 1 is mounted in the mounting hole of valve seat 3 by connector 2, are connect
First 2 and mounting hole in sealing between to be tightly connected, fastener 4 is for connector 2 to be fixed in mounting hole.
Specifically, as shown in Figs. 4-6, pipe fitting 1 is threaded through in connector 2 and fastener 4, and pipe fitting 1 is round tube, in pipe fitting 1
End is equipped with the connector 2 of set on the outside, and center tap 2 is just assembled with pipe fitting 1 in production；It is equipped in mounting hole close
Envelope portion is to be tightly connected between sealing and connector 2 firmly, and in the present embodiment, sealing is that 3 mounting hole of valve seat is arranged in
First conical surface 31 on inner wall, one end of connector 2 are extend into mounting hole, and connector 2 extend into one end in mounting hole and is equipped with the
Two conical surfaces 21 are adapted, by making connector 2 between second conical surface 21 of 2 end of connector and first conical surface 31 of the taper of valve seat 3
First conical surface 31 cooperation of second conical surface 21 and valve seat 3 of end seals to make to be formed between in connector 2 and 3 mounting hole of valve seat
Connection.
Fastener 4 is for connector 2 to be fixed in valve body 6, and in the present embodiment, fastener 4 is nut, and fastener 4 wraps
Ontology 41 and fixed part 42 are included, pipe fitting 1 is worn in ontology 41 and fixed part 42, and fixed part 42 is that 41 one end of ontology is arranged in
The outer surface of cylindrical body, fixed part 42 is equipped with external screw thread, and during installation, fixed part 42 is extend into valve body 6, is set in valve body 6
There is internal screw thread, fixed part 42 is screwed in valve body 6, external screw thread matches that fixed part 42 is made to be fixed on valve body 6 with internal screw thread
It is interior；Meanwhile it being equipped with accommodating cavity 43 in the inside of fixed part 42, the size of accommodating cavity 43 is adapted with the size of connector 2, so that connecing
First 2 can be mounted in accommodating cavity 43, and the depth of accommodating cavity 43 is less than the length of connector 2, so that the part of connector 2 is located at accommodating
In chamber 43, another part is reached outside accommodating cavity 43, and the end face of accommodating cavity 43 is equipped with the inner hole passed through for pipe fitting 1, due to this
The size of inner hole is less than the face size of accommodating cavity 43, and the end face of accommodating cavity 43 can pass through for pipe fitting 1 and can also be with connector 2
